     Although many Chinese students say that their knowledge of English grammar is good, most would admit

that their spoken English is poor. Whenever I speak to a Chinese student they always say, "My spoken English

is poor." However, their spoken English does not have to remain "poor"! I would like to suggest that there may

be some reasons for their problems with spoken English.

     First, they fail to find suitable words to express themselves due to a limited vocabulary. Obviously the better

answer is to expand their vocabulary. However, you can speak with a limited vocabulary, if your attitude is

positive. Others will follow you as long as you use the words that you know.

     Second, they are afraid of making mistakes. Sometimes they make mistakes when they are speaking because

they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY.

Your aim in writing is to be accurate following the rules for grammar and using the right words and spelling the

m correctly. However, in speaking your aim is fluency. You want to get your message across,that is, to talk to

someone in English, as quickly and as well as you can, even though sometimes you may use a wrong word or

tense, but it doesn't matter because the person you are speaking to will understand you and make allowances for

any mistakes he hears.

     The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All that

hearing was necessary for you to start speaking.

     Forth, most Chinese students are reactive rather than proactive language learners. Instead of actively seeking

out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them

and wonder why their English always remains poor. If you have this proactive outlook, then you will see English

opportunities wherever you go.

     If you do not use your English beyond the classroom you will forget what English you know. Remember:

USE IT OR LOSE IT! You can learn how to speak English better by speaking English more.
